Buoyancy is not the result of the water pressure.  Buoyancy is the result of the displaced water weight.  If the net SG of a submersible is greater than 1, then it takes work to surface.  Work = Integral( F*ds ) F > 0.  That work can ideally be identically recovered by resubmerging to the original depth: Work = Integral( F*ds ), sinking F < 0.  If the SG of a submersible is less than 1, then it takes work to submerge:  Work = Integral( F*ds ), F > 0 submerging, and that work may identically be recovered surfacing:  Work = Integral( F*ds ), F< 0. 

Webby,
One of the upside down cup aquarium demonstrations was exactly done to prove that Buoyancy is a FORCE due to PRESSURE .  To understand buoyancy in this context is pivotal to understanding the working of the Zed.

I think MarkE has the wrong end of the stick here.

MARKE,   that pressure equates in the end to volume and this makes it easy to calculate the lift force of uneven shapes is correct.  But in the workings of nature, bouyancy is a FORCE and this has nothing to do with volume/displ.water., but it has all to do with pressure.   It is this way because pressure is directly related to submerged height.(also a volume parameter).  Integral formula's do not aid understanding

  Hi,
     Webby and Sunset, do you pair really understand the implications of Archimedes paradox?

Archimedes Paradox is exactly what I believe I was witnessing in my testing.  However I also saw behavior that led me to believe my test model's proportions were limiting it's performance greatly.  And since I had no easy (meaning cheap) way to test further I stopped and waited for a simulation or better test model to appear. 

The math on this construction is beyond my patience so I could not figure out if there would be a set of proportions (and layers) that could surmount Archimedes Paradox and unity (at best).

Oh how I wish I could see a sim of this particular construction (and not a simplification).
